Patented Apr. 25, 1933 UNITED STATES PATENT OFFICE CHARLES D. BONSALL,OF NEW KENSINGTON, PENNSYLVANIA, ASSIGNOB, TO I. H. KENSINGTON,PENNSYLVANIA, A CORPORATION OF MURPHY'COMPANY, OF NEW' PENNSYLVANIA LOAD'LIFTING ARRANGEMENT Application filed April 18,

The device relates to improvements in railway freightcars which areprovided with load supporting beams extending longitudinally of the carand positioned adjacent the roof. These beams are arranged forattachment of a load lifting device such as chains, ropes, ice'tongs,hooks, etc., which are used to move heavy articles in and out of thecars and move such articles around in the car or to place one part ofthe load over another, such as double decking automobiles. Such a deviceis shown in my Patent No.

1,7 02,961, February 19, 1929.

An object of theinvention is to provide a member capable of movementlongitudinally of such a beam so that the point of. support orsuspension of the load lifting device can be moved longitudinallyof thecar to any convenient or desirable place.

Another object of the invention is to provide a cooperation between theabove mentioned memberand the load supporting beam whereby a downwardlyinclined pull exerted by the load lifting devicebinds the member uponthe beam and prevents or retards its movement longitudinally of thebeam.

- Another object of the invention is to provide an eccentric relationbetween the place of attachment of the load lifting device to the memberand the point or points of contact between the member and the beam sothat a downward pull of the device upon the member binds the member uponthe beam. It may be desirable to have several such members upon eachload supporting beam, for instance, to lift both ends of an automobile.

In the drawings: p

Figs. 1 and 2 show a typical load supporting beam applied to a railwaycar with one of my 'members mounted thereon.

Figs. 3 and ishow the relation between the carlin'e, load supportingbeam and member. Figs. 5 and 6 show a modified construction wherein themember comprises two similar pieces riveted together. f Figs. 7, 8 and 9show-a modified construction wherein the member is made of pressed steelplate. 4 i I Figs. lOand 11 show a modified construction wherein theplace, of attachment of the 1929.

tion wherein the member is offset in a horizontal plane and preferablyformed on, a radius in a horizontal plane.

Figs. 17 and 18 show a modified construction wherein the members areprovided with two apertures or places of attachment of a load liftingdevice.

The load supportingbeam 2 is preferably positioned adjacent the centerof the car or several such beams may be used spaced at intervals betweenthe sides of the car. These beams are preferably attached to andsupported by several carlines 3 and may also form the longitudinal roofframe members ofthecar, such as the ridge pole (as illus-. trated) orpurlins 1. It is desirable that they extend the full length of the carand'have their opposite ends attached to'the opposite end plates 5 ofthe car. i

In the form of my invention illustrated the load supporting beamcomprises a member preferably of an inverted channel section with theweb 7 secured to the carlines 3, spaced, apart walls and oppositelyprojecting flanges 8 at each lower edge of the inverted channel beam.The member 9 is provided with oppositely projecting portions 11 slidablyresting upon the flanges 8 of the load supporting beam and the members 9are also provided with other parts 12.normallybelow and spaced apartfrom the flanges 8'so that the member 9 is normally movablelongitudina-lly of the load supporting beam 2. Means are provided uponthe member 9 for attachment of a load lifting device, such as a hook,ice tong or a rope or chain, which means is positioned between the parts12 and is preferably formed with a depression to position or centralizethe lifting device. When the member is used upon a supporting beam ofinverted channel section, such as shown in Figs. 3 and 4, the means forattachment of the lifting device is positioned below the invertedchannel so that a part of the lifting device may extend within thechannel, thus reducing the vertical space occupied by the member and togive greater clearance between the member 9 and the supporting beam 2,and furthermore, the depression is preferably positioned below theinverted channel.

The parts 12 are in close proximity to the" beam, the member beingprovided with an aperture 17 for insertion of a hook or chain of loadlifting device.

Figs. 7, 8 and9 show a modified form wherein the member 20 is made of apressing having preferably depending flanges 21 adjacent the oppositeside margins of the body of the member to stiffen it and preferably acorrugation 22 to stiffen the returned bends at the ends of the bodywhich form the portions 23 for engagement with the flanges of the loadsupporting beam. A flared aperture 24 may be provided to accommodate thehook or chain of-a load lifting device. a Figs. 10 and 11 show amodified form wherein the member 27 ismade of two similar pieces securedtogether, each having a portion 28 resting upon a flange 29 of the loadsupporting beam 26. The member 27 is pro vided with an aperture 30 orother means for attachment of a. load lifting device, which is not below(i. e. eccentric from) the place of engagement between the portion 28 ofthe member and the flange 29 of the supporting beam, whereby a downwardpull upon the load'lifting device causes the portion 28 to bind betweenthe flange 29 and the upper web of "the supporting beam, thus retardingthe movement of the member 27 longitudinally ofthe beam 2.

Figs. 12, 13 and 14: showa modified form wherein the member has portions36 and 37 resting upon the flanges"34c of the load supporting beam,which portions are provided with oppositely projecting lateralextensions 88 which accentuates the tendency of the member to bind uponthe beam upon a diagonal pull of the load lifting device upon themember.

Figs. 15 and 16 show a modified form wherein the member 40 is providedwith portions ll-'42 resting upon the flanges 44 of the load supportingbeam 2 and the body part 43 of the member, that is, where the loadlifting device is attached to it, is ofl center or eccentric from theplaces of contact of the 7 supporting portions 41 with the flanges ofthe beam so that a downward pull upon the load lifting device binds themember upon the load lifting beam and retards its movementlongitudinally of the beam.

Figs. 17 and 18 show a modified form wherein themember 46 is providedwith two apertures 47 or places of attachment for the load liftingdevice, eitherone of which is positioned eccentric from the place ofsup= port of the member upon the beam.

Figs. 12 and 13 and also Fig. 15 show load supporting beams havinglateral flanges for supporting the members which are upwardly inclinedso that ice .tongs or similar means of attaching a load lifting deviceto the beam between the members will'notslipoif. Such beams are nowin'gener'aluse. The-portions of the members whichbi'nd uponthe lowersurfaces of the flanges of the beams" are preferably similarly inclined.

g The two piece members, such as shownin Figs. 5, 10 and 17, aredesirable to facilitate application of the member to cars alreadyequipped with a load lifting beam as' they can be riveted or boltedtogether after the lsjeparate members are associated "with the eam.

The accompanying drawingsillustrate the preferred form of the invention,though it is to be understood that the inventi'onis not limited to theexact details of construction shown and described, as it is obvious thatvarious modifications thereof, within the scope of the claims, willoccur to persons skilled in the art.
